The REFORM study, a  randomized controlled trial , assessed the efficacy of a biolimus-coated balloon (BCB) against a paclitaxel-coated balloon (PCB) for treating  in-stent restenosis (ISR) . While drug-coated balloons are a proven treatment for ISR, this study aimed to determine if a BCB was non-inferior to the established PCB. The study  failed to demonstrate non-inferiority  of the BCB, with th...

The paper  examines patient selection criteria, procedural techniques, and post-procedure care , including management of complications like conduction disturbances and bleeding. It  details various TTVR systems and their char...

This research review article from  Circulation: Cardiovascular Interventions  focuses on managing large-bore vascular access (≥12 French) during transfemoral procedures, such as heart interventions and electrophysiology.   The authors explore optimal puncture techniques , including ultrasound guidance, and  various hemostasis strategies , comparing suture-based and plug-based vascular closure devi...

This JACC manuscript details a first-in-human study evaluating the Magenta Elevate, a novel high-output mechanical circulatory support (MCS) catheter. The study assessed its safety and efficacy during high-risk percutaneous coronary intervention (PCI), particularly in left main coronary artery interventions. Results showed the device to be safe, with no major adverse events, and effective in maint...
